Western Star Resources accelerates U.S. tungsten strategy with three assets, 2026 drilling plans

Western Star Targets 2026 Maiden Drilling at Eagle Point to Test Historical Mineralization and Potential Extensions as Company Advances Three U.S. Tungsten Projects

Vancouver, British Columbia – TheNewswire - 4 th August 2026 – Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) (the “Company” or “Western Star”) is pleased to provide a corporate and exploration update following a significant period of growth, during which the Company assembled and began advancing a portfolio of past-producing tungsten assets in the United States.

Since the end of 2025, Western Star has:

Built a portfolio of three active U.S. tungsten projects across Nevada and New Mexico;

Expanded the past-producing Rowland Tungsten Property by approximately 170%;

Acquired the adjacent past-producing White Star Tungsten Project, creating an approximately six-kilometre prospective exploration corridor across the Company's Nevada position;

Acquired a 100% interest in the past-producing Eagle Point Tungsten Project in New Mexico;

Commenced modern systematic exploration programs at Rowland and White Star;

Completed high-resolution UAV magnetic geophysical work and extensive surface exploration;

Identified an approximately one-kilometre tungsten-skarn geochemical corridor at Rowland, including a peak soil result of approximately 1,425 ppm WO , equivalent to approximately 0.14% WO

Commenced drill-permitting activities at Rowland;

Engaged Dahrouge Geological Consulting to assist with the evaluation and future exploration of the Company's Nevada and New Mexico tungsten assets;

Begun technical work aimed at defining drill targets across the known surface mineralization at Eagle Point;

Targeted a maiden Eagle Point drill program during 2026, subject to permitting, final program design and other customary considerations;

Closed approximately C$3.69 million through an oversubscribed private placement; and

Submitted an application in response to a U.S. Defense Industrial Base Consortium solicitation relating to reliable supplies of strategic critical minerals.

Western Star has now moved beyond portfolio assembly. The Company’s focus is on disciplined execution: advancing priority targets toward drilling, testing for discovery and establishing the scale of its U.S. tungsten platform.

THREE PAST-PRODUCING U.S. TUNGSTEN PROJECTS

Western Star's U.S. tungsten portfolio now provides exposure to three historically productive tungsten systems:

EAGLE POINT – NEW MEXICO

Historical production of approximately 1,800 tons of scheelite-bearing material, historical U.S. Government estimates outlining significant near-surface tungsten-bearing material, eight historically mapped skarn bodies, modern USGS sampling returning up to 27.6% WO ₃ and 0.98% Mo, and a U.S. Government-supported exploration program that was planned but never executed.

ROWLAND – NEVADA

Historical production exceeding approximately 1,000 tons, with historical reported grades reaching approximately 3.38% WO ₃ . Western Star has expanded the property approximately 170%, identified more than 17 historical workings and completed the first phase of an integrated modern exploration program designed to advance targets toward drilling.

WHITE STAR – NEVADA

Part of a broader historical tungsten-mining complex with reported historical production of approximately 10,000 tons grading approximately 1.0% WO ₃ during 1954, together with additional historical production in 1956. Its acquisition provides Western Star with a substantially larger district-scale exploration position adjoining Rowland.

Historical production and historical estimates referenced herein have not necessarily been independently verified by the Company and should not be considered indicative of future results. Historical estimates are not current mineral resources or mineral reserves.

EAGLE POINT – FROM HISTORICAL ESTIMATE TOWARD MODERN RESOURCE DEFINITION

Eagle Point is a key asset within Western Star’s U.S. tungsten portfolio.

The Company's objective is to systematically test the historically identified mineralization using modern exploration and drilling and, if supported by sufficient geological and analytical data, advance Eagle Point toward the potential preparation of a maiden mineral resource estimate in accordance with NI 43-101.

Historical U.S. Government work identified substantial near-surface tungsten mineralization through trenching, surface sampling and geological mapping. Historical estimates reported various tonnage and grade ranges, including approximately 100,000 to 150,000 tons grading approximately 0.5% WO ₃ , while other historical government examinations outlined approximately 150,000 to 200,000 tons of scheelite-bearing material.

These estimates are historical in nature.

A Qualified Person has not completed sufficient work to classify the historical estimates as current mineral resources or mineral reserves, and Western Star is not treating the historical estimates as current mineral resources or mineral reserves. They should not be relied upon.

Western Star intends to evaluate the geological basis of that historical work through modern exploration and drilling. The planned program is designed not only to test historically identified mineralized areas, but also to assess whether tungsten-bearing skarn mineralization continues along strike , at depth or into areas that received limited historical attention .

This provides Western Star with two distinct exploration objectives at Eagle Point:

1. RESOURCE DEFINITION

Drill the historically identified mineralized zones with sufficient modern geological, analytical and QA/QC information to determine whether the data can ultimately support the preparation of a maiden NI 43-101 mineral resource estimate.

2. RESOURCE EXPANSION POTENTIAL

Test extensions of the known skarn bodies along strike and at depth, together with additional historically mapped skarn occurrences and targets generated through modern geophysics, mapping and geochemistry.

There can be no assurance that exploration will result in the definition of a mineral resource or that mineralization will extend beyond historically identified areas.

WHY EAGLE POINT STANDS OUT

Several attributes make Eagle Point a priority for Western Star:

PAST PRODUCTION

Approximately 1,800 tons of tungsten-bearing material was historically mined and shipped from Eagle Point, with historical grades reported at approximately 0.5% WO ₃ .

HISTORICAL U.S. GOVERNMENT ESTIMATE

Historical federal exploration work outlined significant near-surface tungsten-bearing material through trenching and surface sampling.

EXCEPTIONALLY HIGH-GRADE MODERN SURFACE SAMPLE

USGS/NMBGMR sampling returned a selective composite skarn-outcrop sample grading:

27.6% WO ₃

219,000 ppm tungsten

0.98% molybdenum

The sample is selective in nature and is not necessarily representative of average mineralization across the Property.

MULTIPLE MINERALIZED SKARN BODIES

Historical mapping identified approximately eight separate skarn/tactite bodies around the principal workings.

LIMITED HISTORICAL DRILLING

Despite the extensive surface work, the system received very limited historical drilling.

U.S. GOVERNMENT-BACKED EXPLORATION

During the 1950s, the U.S. Government entered into a Defense Minerals Exploration Administration agreement to support further exploration of Eagle Point.

The proposed program included underground development and diamond drilling , but was never executed.

Consequently, several of the principal exploration objectives identified during the historical government work remained untested.

2026 EAGLE POINT DRILLING STRATEGY

Western Star has engaged Dahrouge Geological Consulting to assist with technical evaluation and future exploration across the Company's tungsten portfolio.

At Eagle Point, this work is focused on integrating historical geological information with modern datasets and building a practical geological model to support drill targeting .

The Company’s near-term objective is to design a program capable of systematically testing the historical , non-compliant estimate.

Subject to permitting, final drill design, contractor availability and other customary considerations, Western Star is targeting a maiden drill program at Eagle Point during 2026. The program would represent an important step in advancing Eagle Point from a historically recognized tungsten occurrence toward modern exploration and potential resource definition. Western Star intends for drilling to:

Test the principal historically identified mineralized zones;

Investigate grade and geological continuity;

Test the geometry and thickness of tungsten-bearing skarn;

Provide modern geological and analytical information;

Test selected extensions along strike and at depth;

Evaluate additional targets generated through modern exploration;

Provide information that may, if sufficient, support future mineral-resource estimation; and

Establish the geological framework required for subsequent, potentially larger exploration campaigns.

THE OBJECTIVE: DEFINE, THEN EXPAND

Western Star’s strategy at Eagle Point is straightforward :

Validate the historical geological model.

Drill the historically identified mineralization.

Establish continuity.

Test extensions.

If supported by results, advance toward a maiden NI 43-101 mineral resource estimate while continuing to evaluate the broader scale of the system.

A HISTORICAL U.S. GOVERNMENT TARGET MOVING TOWARD MODERN DRILLING

Blake Morgan, President and CEO of Western Star Resources, commented:

“ Eagle Point is an important opportunity for Western Star because we are not starting from first principles.

The project has historical production , historical U.S. Government exploration, multiple skarn bodies exposed at surface, historical estimates of tungsten-bearing material and modern USGS sampling that returned up to 27.6% WO ₃ . A government- supported program was once planned to advance Eagle Point through underground development and diamond drilling , but that drilling was never completed.

Our goal is to bring modern exploration standards to that historical opportunity. We intend to drill the historically identified mineralization and generate the geological and analytical information required to determine whether Eagle Point can support a maiden NI 43-101 mineral resource estimate. At the same time, we intend to test beyond the historical footprint .

With eight historically mapped skarn bodies, high-grade tungsten exposed at surface and limited drilling across the broader system, we believe Eagle Point warrants a systematic program that evaluates both the known mineralization and its potential extensions along strike and at depth.

Rowland is also moving toward drilling in Nevada , and White Star gives us an adjoining district-scale exploration opportunity. In less than a year, Western Star has assembled three past-producing U.S. tungsten projects, strengthened its balance sheet , put technical teams in the field and begun moving these assets toward drilling. The next phase is execution .”

FROM ACQUISITION TO DRILLING

Western Star’s progress since the end of 2025 has positioned the Company for a new phase of development.

The Company's strategy has progressed through three stages:

ACQUIRE – Assemble past-producing tungsten assets in established U.S. mining jurisdictions.

DEFINE – Apply modern geophysics, geochemistry, mapping and geological modelling to identify and prioritize drill targets.

DRILL & EXPAND – Test historical mineralization, evaluate extensions and, where supported by sufficient data, advance projects toward maiden mineral resource estimates.

Western Star believes the combination of historical production, high-grade tungsten occurrences, multiple untested targets, modern exploration programs, a strengthened treasury and exposure to U.S. critical-mineral supply priorities provides a differentiated position within the North American tungsten exploration sector.

2026 IS ABOUT EXECUTION

With Rowland advancing toward drilling, White Star undergoing its first integrated modern exploration program and Eagle Point being prepared for a maiden drill campaign, Western Star intends to advance its U.S. tungsten portfolio in a disciplined and systematic manner through the remainder of 2026. The Company’s objective remains clear:

Discover and define meaningful domestic tungsten resources capable of contributing to a secure North American critical-mineral supply chain.

There can be no assurance that exploration will result in the discovery or definition of a mineral resource or an economically viable mineral deposit.
